Product Description:
The RLB2-021DBB is a motor power cable from Bosch Rexroth Indramat that belongs to the RLB Motor Power Cables series. It links MS2 synchronous motors to ctrlX inverters, carrying three-phase power while maintaining signal integrity in dynamic machine axes. By combining industrial connectors with flexible conductors, the cable simplifies energy distribution in automation cells.
Engineered for repetitive motion, the cable withstands 5,000,000 bending cycles in drag-chain applications. Its copper conductors present a cross section of 1.5 mm², providing adequate ampacity for low-power servo axes while limiting overall diameter. Power termination is via an M23 (SPEEDCON) plug, enabling quarter-turn locking and quick exchange on the machine. Mechanical abrasion is resisted by a PUR (Orange RAL 2003) outer jacket that also meets typical oil-coolant requirements. The phase cores are insulated for a line-to-line rating of 600/1000 V, so the assembly supports standard drive DC-link voltages without additional protection.
During motion, the assembly may flex down to a minimum dynamic radius of 7.5×D, whereas static routing can tighten to 5×D for compact cabinet runs. Electrical compatibility is tuned to the ctrlX DRIVE family, matching pin-out and shield strategy defined by that controller platform. On the motor side it mates with the MS2(X) generation, and the motor connection code U inside the type designation confirms the required pin arrangement. The cable follows a Basic design within the Rexroth Cables product group and is classified as a power cable, with auxiliary signal pairs protected for 450/750 V. These features support predictable installation lengths and reduced commissioning time.
